Application filed June 8. 1921. Serial No. 475,921.

The invention relates to new and useful improvements in jar closures,and more particularly to a metal closure adapted to be used inconnection with a lass or porcelain jar having a 'substantia ly straightor vertical outer wall with which the closure makes gripping contact.

An object of the invention. is to provide a jar closure having adepending flange adapted to extend down along side of the outer wall-ofthe jar with spaced, elongated, vertically disposed projections whichare adapted to grip the side wall of the jar and hold the closurethereon. A further object of the invention is to provide a jar closureof the above type wherein the inner face of the flange and theprojections are coated with a sealing material which is adapted to bescraped from the projections when the closure is forced onto the jar andpacked between the flange and the wall of the jar to aid in sealing thesame.

These and other objects will\ in part be obvious and will in part behereinafter more-fully disclosed. In the drawings, which show by way ofillustration one embodiment 9f the invention- Figure 1 is a side view ofthe upper portion of a jar showing my improved closure applied thereto;Fig. 2 is a enlarged sectional view of the closure and showing in dottedlines the upper portion of a jar;

Fig. 3 is a still further enlarged vertical section of a portion of theclosure before being applied to the jar; .1

Fig. 4 is a view similar to Fig. 3, but showing the closure applied tothe jar and the sealing material scraped from the projections and packedbetween the flange and the side wall of the jar.

My improved closure is'preferably made of sheet metal and consistsbroadly of a top portion having an integral depending flange,

- said flange at the lower portion thereof being referably bentoutwardly and thence inwar y toform a strengthening bead for the flangeis provided with a series of elonthe lower portion of the flange. Thisalso gated closely spaced vertical projections detail to the drawings,v

wardly at 7 to form a strengthening bead for the lower portionof theflanga- The I inwardly bent portion 7 terminates so that the extremelower edge thereof lies in a circle of larger diameter than the innerdiameter of the flange 5, and this forms a relatively large entranceopening for the jar when the closure is placed on the jar.

The portion of the flange above the strengthening bead is substantiallyvertical, andsaid vertical portion of the flange is formed with a seriesof vertically disposed ribs spaced from each other a slight distance andprojecting inwardly from the flange. The inner face of the flange,including the projections, is coated with sealing material 9. The topportion 4 of the closure is bent so as to form an annular groove 10which is adapted to engage over the upper edge of the j arv 11. Thesealing material 9 also lines the inner face of the groove 10. The innerdiameter of the flange 5 is slightly greater than the outer diameter ofthe ar. The distance from the inner face of one projection 8 to adiametrically opposedprojection 8 is slightly less than the outerdiameter of the jar.

When the closure is forced onto the jar,

the sealing material which covers the projections will be scraped offfromthe projections b the outer extreme edge of the jar and will ecarried upwardly and crowded in between the outer wall of the jar andthe inner wall of the flange 5 above said projections. This packing ofthe sealing material in between the flange of the side wall of the jaraids materially in eflecting the per-' Furthermore, the sealfect seal ofthe jar. ing'material is stripped from the inner face of the projectionss0 thatthe metal will contact with the outer surface of the jar andfirmly'grip the same. The projections 8' are closely spaced. Eachprojection is capable of reshaping itself independent of the others. Ifthe jar is out-of-round, certain ofthe projections at the maximumdiameter of the arwill be more or less flattened or reshaped while theprojections Eat the minimum diameter of the jar will be less flattenedor reshaped and will grip-the outer wall of the.

jar. Thus it is that the projections will grip the jar all the wayaround even though it is out-of-round and without causing any materialdistortion of the circular depending flange 5.

By making the projections elongated in a vertical direction, I am ableto secure an extended gripping surface "and, at the same time,preservea'll the a vantages of the relatively short'pi'ojections in acircumferential direction about the jar. It will readily be seen that bymaking the projections short in a circumferential direction and closelyspacing the same, I am able to get a much bettergripping surface wherethe jar is out-ofround, rough or misshaped i'nx any way.

It is obvious that minor" changes in the details of construction may bemade without departing from the spirit of the invention as set forth inthe appended claim.

Having thus described the invention, what is claimed asnew is A, jarclosure comprising a top portion and a depending straight verticalflange having its inner diameter larger than the outer diameter ofthe'jar mouth to be closed thereby, said flange having inwardlyextending spaced vertical ribs or projections, the inner faces of whichare substantially parallel conforming to any out-of-roundness in theglass, and each rib caused to grip the outer wall of the jar.

In testimony whereof, I afiix my signature. Y Y
